【Abstract】 Based on the tank shaped transformer and theory of transcutaneous energy transmission(TET),the finite element software is used to simulate the magnetic circuit coupling function to calculate the loss and volume heat generation rate of the core and coil of the transcutaneous transformer.The temperature field of transformer is analyzed by the multi-physics coupling of electromagnetic field,fluid solid field and temperature field.A method of stabilizing the absorbed power of the implanted device is proposed by monitoring the temperature rise of the secondary coil and then adjusting the input power of the primary coil,so that the implanted device to stabilize the power of about 32 W,greatly improving the system stability and reliability.更多还原
